BOTTLE.

SPECIFICATION forming part of Letters Patent Ne. 595,499, dated December 14, 1897. 1 Application filed January 5, 1897. Serial No. 618,082. (No model.) 7

To all whom it may concern: 4

Be it known that I, DAVID ROBERT SAUN- DERS, a citizen of the United States, residing following is a full and complete specification,

such as will enable those skilled in the art to which it appertains to make and usethe same.

This invention relates to bottles, j u gs, jars, and similar vessels; and the object thereof is to provide an improved vessel of this class the neck of which is formed in such manner and provided with attachments so constructed that when the vessel has been filled and the attachment applied the vessel may be emptied of its contents, but cannot be refilled or reused.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which I have shown my invention applied to a bottle, and in which Figure 1 is a central vertical section of the upper part of a bottle and the neck thereof, provided with my improvement; Fig. 2, a section on the line 2 2 thereof 5 Fig. 3, a section on the line 3 3; and Fig. 4, a section of a modified detail of the construction.

In the drawings forming part of this specification, the separate parts of my improvement are designated by the same numerals of referencelthroughout the several views, and in the practice of my invention I provide a bottle 5, having a neck 6, the inner walls of which are enlarged or thickened, so as to form a small bore or passage 7, above which the walls of the neck are conical in form, as shown at 8, whereby a conical chamber 9 is formed, the base of which is directed upwardly, and at the upper end of the conical chamber 9 is an inwardly-directed shoulder or projection 10, at a predetermined distance above which is formed an annular groove 11, which is rectangular in cross-section and by reason of which an annular shoulder or projection 12 is formed in the outer walls of the neck. I also provide a disk or plug 13, in the perimeter of which is formed a small annular 5o groove 14, which is also angular in cross-section, and mounted in the annular groove 14 in the disk or plug 13 is an' open spring-ring 15, which is provided with outwardly-directed loops 16, and the lower side of the diskor plug 13 is provided with radial ribs or projections 17, three of which are shown in Fig. 3, and said disk or plug 13 is also provided with a central vertical port or passage 18. I also provide a small spherical valve 19, composed of cork or similar material, and which is adapted to close the port or passage 7 in the neck 6, and above this is placed a larger spherical ball or body 20, which is preferably composed of glass or similar material, and above this is placed another larger spherical ball or body 21, which is also composed of glass or similar material, and when these parts are placed in position, as shown in Fig. l, the vessel being held in an upright position, the spherical ball or body 21 will be above the inwardly-directed annular shoulder or projection 10, while the spherical ball or body 20 will be below said shoulder or projection;

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

In this class of devices the bottle or Vessel is first filled before the neck attachment is applied, and the bottle 5 having been filled the valve 19 is dropped into position. The spherical ball or body 20 is then placed in position thereon, after which the spherical ball or body 21 is inserted into the neck and rests upon the ball or body 20, the latter resting on the valve 19, and the plug or disk 13 is then secured in place by forcing it downwardly into the neck until the groove 14 therein registers with the groove 11 in the neck, when the loops 16, formed on the springring 15, will be thrown outwardly into the groove 11 by thespring operation of the ring 15, and said disk or plug will be securely held within the neck of the bottle and cannot be removed without breaking off the neck. When the parts are thus connected, the disk or plug 13 will be a short distance above the ball or body 21, this distance being sufiicient to allow said ball or body 21, the ball or body 20,

and the valve 19 to move when the bottle is inverted sufficiently to open the port or passage 7.

IVhen the parts have been assembled as above described, the neck of the bottle may be closed by a cork or stopper in the usual through the port or passage 18 in the disk or plug 13.

The radial ribs 17 on the bottom of the disk or plug 13 are intended to prevent the ball or body 21 from closing the port or passage 18 when the bottle is inverted, and it will be understood that this operation of pouring out the contents of the bottle may be continued or repeated until the bottle is entirely empty.

If an attempt be made to refill the bottle by pouring liquids thereinto, the valve 19 will at once be reseated under the action of gravity and the balls or bodies 20 and 21 and no liquids can enter the bottle, and this operation of the valve will be the same in any position in which the bottle can be held in an attempt to fill the same by pouring liquids thereinto.

By forming the valve 19 of cork it is adapted to serve as a float, and this device will also prevent the filling of the bottle by forcing liquids thereinto, said valve rising to its seat, as will be readily understood, and this operation of the valve would be the same if the bottle were immersed neck downward into the liquids with which it is desired to fill it.

My invention is not limited to the material of which the valve and the balls or bodies 20 and 21 are composed; but the valve 19 should be made of some light material and the bodies or balls 20 and 21 should be made of glass or other heavy material in order to secure the operation thereof, as herein described.

The arrangement of the ball or body 21, the annular inwardly-directed shoulder 10, and the port or passage 18 in the disk or plug 13 is such that a wire, tool, or other instrument cannot be inserted and successfully operated in an attempt to interfere with the operation of the valve, and it will thus be seen that I accomplish the object of my invention by means of a device which is simple in construction and operation and comparatively inexpensive.

It will be seen that the space around the spherical ball or body 20 is much larger than that around the ball or body 21, and said ball or body 20 is ofjust such size as to pass through the annular inwardly-directed shoulder or projection 10, and if a wire or other instrument the proper size to fit tight is pushed over the larger ball or body 21. and drawn back thereof, holding up said ball or body, the said Wire or instrument would be entirely too loose to hold up the small ball or body 20, owing to the fact that the space around the same is greater than that around the upper ball or body 21.

Instead of making the disk or plug 13 of glass I may make the same of metal, and in this event I employ the construction shown in Fig. 4, unless the metal employed be such that will not corrode or be injuriously afifected by fluids or acids.

In the construction shown in Fig. 4 I employ a ring or annular plug 23, in which the annular groove 14 is formed, and secured to the bottom thereof is a disk 24, of cork,which is provided centrally with an upwardly-directed tubular extension 25,which passes centrally through the ring or plug 23, and the upper end of which is adapted to be closed bya plug or stopper 26, and I also form on the under side of the disk or plate 24 the radial shoulders or projections 14, and when this device is secured in the neck of the vessel the operation will be substantially the same as hereinbefore described.

The object of employing the cork disk 24 is to prevent the contents of the bottle from coming in contact with the ring or plug 23, and I also form that portion of the neck of the bottle in which the groove 11 is formed very thin, so that an attempt to. pull out the disk or plug 13 will result in breaking out the walls of said groove in which said spring is located.

It will be understood that when the plug or stopper 26 is employed the usual cork or stopper may be employed for closing the neck of the bottle, and it will be apparent that changes in and modifications of the construction herein described may be made Without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a non-refillable bottle, the combination with a neck having an inverted conical chamber 9 therein the lower end of which opens through a contracted passage '7 into the body of the bottle, and at the upper end of which the neck of the bottle is provided with an internal annular rib 10 of a small spherical float-valve 19 fittingin said conical chamber and adapted to close said contracted opening 7 a larger heavy ball 20 adapted to pass closely through said annular rib 10 into said conical chamber and to bear upon said floatvalve 19 a third and still larger heavy ball 21 adapted to fit into the neck of the bottle above said annular rib and to bear through the reduced opening formed by said annular rib 10 upon said ball 20, and hold the latter in said conical chamber; and a locking-plug provided With a central opening therein, fittingin said bottle-neck above said ball 21, and adapted to confine said ball therein, substantially as described.

2. In a non-refillable bottle, the combina-' tion with a neck having an inverted conical chamber 9 therein, the apex of which opens through a contracted passage 7 into the body of the bottle, and at the base of which the neck of the bottle is provided with an internal annular rib 1O of a small spherical floatvalve 19 fitting in the apex of said conical chamber and adapted to close said contracted opening 7; a larger heavy ball 20 of approximately the same diameter as the opening through said annular rib, fitting in the base of said inverted conical chamber, and adapted to bear upon said fioat-valve'19; a second DAVID ROBERT SAUNDERS.
